Overview
- The TP-Link ISM311LS and ISM311LM industrial SFP transceiver modules are engineered for deployment in demanding environments where standard network equipment cannot reliably operate. These single-mode and multi-mode variants provide 1000 Mbps fibre connectivity with support for 1000Base-LX (long-distance single-mode) and 1000Base-SX (short-distance multi-mode) transmission standards.
Designed to operate across an extended temperature range of -40 to 85°C, these modules are ideal for industrial facilities, outdoor deployments, and locations subject to extreme environmental conditions. The hot-pluggable form factor allows technicians to install or replace modules without interrupting network service, minimising downtime during maintenance or expansion.
Built to the SFP-MSA standard, these transceivers are compatible with a wide range of network switches, routers, and media converters from multiple vendors. Digital Diagnostic Monitoring capability enables network administrators to monitor transceiver status, temperature, power levels, and optical signals in real time, supporting proactive maintenance and rapid issue diagnosis.

FAQs
What is the difference between the ISM311LS and ISM311LM modules?
The ISM311LS is a single-mode transceiver supporting 1000Base-LX transmission over longer distances (typically up to 10 km), while the ISM311LM is a multi-mode transceiver supporting 1000Base-SX transmission over shorter distances (typically up to 550 m). Choose based on your required transmission distance and fibre type.
Can these SFP modules work in standard network equipment?
Yes. Both modules comply with the SFP-MSA standard, making them compatible with any SFP-capable network switch, router, or media converter from any vendor, provided it supports the corresponding transmission standard (1000Base-LX or 1000Base-SX).
What does Digital Diagnostic Monitoring (DDM) provide?
DDM allows real-time monitoring of transceiver parameters including optical signal power levels, temperature, voltage, and bias current. This enables proactive monitoring and faster troubleshooting of network issues without removing the module.
Are these modules suitable for industrial environments?
Yes. The ISM311 series is specifically designed for industrial use, with an extended operating temperature range of -40 to 85°C, making them suitable for outdoor installations, manufacturing facilities, and other harsh environments where standard transceivers would fail.
Can I hot-swap these modules during operation?
Yes. Both modules are hot-pluggable, allowing you to insert or remove them without powering down your network equipment, providing flexibility for maintenance and network reconfiguration with minimal service interruption.
What warranty is provided with these modules?
These modules come with a 36-month (3-year) manufacturer's warranty, covering defects in materials and workmanship.
What type of fibre should I use with each module?
The ISM311LS requires single-mode fibre for 1000Base-LX transmission, while the ISM311LM requires multi-mode fibre for 1000Base-SX transmission. Ensure your fibre infrastructure matches the module type to achieve optimal performance.
